Why Liquid Pipe Cleaners are Bad for Your Pipes

A lot of people use liquid pipe cleaners like Liquid Plumber and Drano to get rid of clogged drains. These products claim to be quick and easy ways to clear out clogs, but they have big problems that can hurt your plumbing over time. To keep your plumbing system healthy and long-lasting, you need to know why liquid pipe cleaners are bad for your pipes. Here are some reasons you might want to think twice about using these chemical solutions instead of safer, more effective ones.

The Composition of Liquid Pipe Cleaners

Most liquid pipe cleaners are made from strong chemicals that are meant to quickly break down organic matter. Usually, the main active ingredients are:

  • Sodium Hydroxide (Lye): A strong base that can dissolve grease, hair, and other organic materials.
  • Sodium Hypochlorite (Bleach): Often used to sanitize and break down materials.
  • Aluminum: When mixed with lye, it makes heat and gas, which helps to clear out clogs.

These ingredients may help clear out clogs, but they can also damage your plumbing in a number of ways.

How Liquid Pipe Cleaners Damage Your Pipes

Corrosion and Pipe Damage:

The chemicals that make up liquid pipe cleaners are very acidic. When used over and over, they can wear away at the inside of your pipes, causing them to thin and eventually leak. A lot of damage can be done over time by this corrosion, especially to older pipes made of galvanized steel or cast iron. The harsh chemicals can weaken even modern PVC pipes, which can cause them to crack and break.

Heat Generation:

A lot of heat is made when these cleaners are used because they cause chemical reactions. This heat can bend or melt PVC pipes and make the plumbing system’s joints and seals less strong, which makes leaks and bursts more likely. Older metal pipes may also expand and contract because of the heat, which can cause more problems with the structure.

Toxic Fumes:

Putting liquid pipe cleaners together with other household chemicals, like ammonia or other cleaners, can make poisonous fumes that are bad for your health. The fumes can also stay in your pipes and make the air in your home less healthy. The danger is greatest in places that don’t have enough air flow, like basements or small bathrooms.

Partial Clog Clearing:

Most of the time, liquid pipe cleaners only work temporarily. Some of them may get rid of the clog well enough for water to flow through, but they often leave behind residue that can cause new blockages. This keeps happening over and over, which makes the damage to your pipes worse over time. The chemicals that are left behind can also bring in more trash, which can make the problem worse in the long run.

Environmental and Health Concerns

Besides harming your plumbing, liquid pipe cleaners are also bad for the environment and your health:

Water Contamination

Some of the chemicals in these cleaners can get into the groundwater and make it dirty. This is bad for both the environment and people’s health. Getting rid of these chemicals can also hurt wildlife and mess up ecosystems.

Skin and Eye Irritation

Handling liquid pipe cleaners can make your skin and eyes very irritated and burn them. Ingestion by accident can be very dangerous and needs medical help right away. Pets and little kids are also at risk because they might touch residues that are left on surfaces.

Safer Alternatives to Liquid Pipe Cleaners

Because liquid pipe cleaners can be dangerous, you might want to look into safer ways to clean your drains and keep your plumbing in good shape.

Enzymatic Cleaners

There are no harsh chemicals in enzyme-based pipe cleaners because they use natural bacteria and enzymes to break down organic matter. Your pipes and the earth are safe from them. When your pipes get clogged again, ask your plumber what enzymatic pipe cleaners they like. These cleaners take longer to work than chemical ones, but they are safer and last longer.

Professional Drain Cleaning

If the clogs don’t go away or get worse, you should call a professional. A plumber can help keep your plumbing in good shape and keep your drains from getting clogged up by cleaning them on a regular basis. Professionals know how to clear out clogs without damaging your pipes because they have the right tools and know-how.

Preventative Measures for Healthy Drains

Stopping clogs before they happen is always better than fixing them. These tips will help keep your drains clear and cut down on the need for harsh cleaners:

Use Drain Covers:

Put drain covers on your sinks, showers, and tubs to keep hair, food, and other things from going into your pipes. These easy-to-use tools can keep many common clogs from happening.

Dispose of Grease Properly:

Do not put oil or grease down the drain. Leave it to harden, then throw it away in the trash. When grease hardens in your pipes, it can cause serious blockages that are hard to get rid of.

Regular Maintenance:

To keep your plumbing system in good shape, have it checked out and cleaned on a regular basis. Potential problems can be found and fixed by a professional before they get worse. Putting money into regular maintenance can save you cash in the long run.

Mind What Goes Down the Drain:

Pay attention to what you flush or wash down the drain. Don’t throw away things that won’t break down and use strainers to catch bigger pieces. Things like paper towels, feminine hygiene products, and even some kinds of food can really clog things up.

Common Myths About Liquid Pipe Cleaners

Because they are still very popular, there are a few myths about liquid pipe cleaners that keep people using them:

Myth: Liquid Pipe Cleaners are Safe for All Pipes

A lot of people think that liquid pipe cleaners are safe for all types of plumbing because they can be bought. It’s not true. The harsh chemicals can hurt many kinds of pipes, especially older ones or ones made of materials that don’t last as long.

Myth: They Provide a Permanent Solution

Another common misunderstanding is that liquid pipe cleaners can clear out clogs for good. In reality, they usually only work for a short time, which means that problems keep happening and they have to be used again and again.

Myth: More is Better

Some homeowners believe that adding more product will help clear the clog more quickly. But using too much liquid pipe cleaner can make the damage to your pipes worse and raise the risk of dangerous fumes.

Overall

Liquid pipe cleaners may seem like an easy way to clear clogged drains, but they aren’t the best choice because they damage your plumbing and the environment over time. The corrosive chemicals can hurt your pipes, which could cost a lot to fix and could be bad for your health. You can keep your plumbing in great shape without the risks that come with liquid pipe cleaners by choosing safer alternatives and keeping your drains in good shape through preventative measures.

If you’re dealing with persistent clogs or want to ensure the health of your plumbing system, consider reaching out to a professional plumber. They can provide expert advice and services to keep your drains clear and your pipes in top shape. For reliable and thorough service, consider scheduling regular good ole fashion drain cleaning from a plumber to maintain your plumbing system and avoid the pitfalls of chemical cleaners.

We live in a tri-level home and we were having a sewer back-up issue in our basement shower. Called Nick first thing in the morning and he had a technician out the same day. Technician was very helpful and efficient. Would recommend them for any sewers issues you may have. Pricing is also great and I will continue to do annual clean-outs with them.

After a frustrating first call/service with Simply Sewer, Nick, the owner came out and made things right – I appreciated his integrity and commitment to making things right. He was also respectful and kind to his employee, which I always appreciate seeing in a boss. Would recommend.
